Yes I was skeptical that this product wasn't worth it because it's cheaper than the competition. But I just went ahead and bought it, and guess what? It's even better than $60-$80 headphones. How is it better? Well for starters it fits, no it doesn't fall from your ears which is something I really hate. Are you one of those people who have a hard time with letting the headphones stay in your ears? Does it happen often that the headphone on your left ears fall first? Then you should try these headphones, and, you won't be disappointed! I have tried them while running, doing jumping jacks and Burpees and they stayed fit. Good job Sony

I bought these earphones because I wanted something to take with me on a road trip. I made the mistake of not testing them out before we got on the road. The sound quality is absolutely terrible; no bass and ridiculous amounts of distortion before I even get my music player's volume level up to 50%. I'd have returned these if I hadn't just had blind faith in my previous experiences with Sony products and tossed the packaging before we left.

I have owned this headset for only one day, so I cannot address its durability. But I read the other reviews here and I have a very different opinion on its fit and sound quality. I have trouble finding an earbud that fits into my ears, everything is too large and ends up falling right out. I have, therefore, always used a headset that sits on my head and over my ears rather than earbuds. But this style fits around the ear, is slightly adjustable for size and somehow the bud is small enough to fit comfortably and stay in place. It doesn't look smaller, so maybe it's the design. I have found most headsets to be somewhat lacking in a really good bass response, but this is pretty good. The way you place it does seem to matter, but once I have it where I want it, it stays put and the sound quality is very acceptable.

I was using these "active sport" headphone when I would do cardio and some workouts. Just today the left ear bud volume became drastically lower than the right. I don't know what to do because I loved them up until today.
